Seriously, NewburyToday, why peddle such inanities like this?
I live in the north of Thatcham; immediately after the lightning the sky in my back garden was full of stars whereas the front of my house contained a Cumulonimbus cloud (the only cloud-type to produce lightning) in the not-too-far distance, moving at a moderate rate.
It was absolutely chucking it down a number of minutes prior, as Cumulonimbus clouds do, so my 'theory' was that it could very well have been a bolt from the blue - when lightning strikes outwards from within the cloud, sometimes up to 10 miles away.
All of this meteor theorising is just, IMO, wishful thinking; people crave the unexplainable (look at religion).
PS: It's not rare for Cumulonimbus clouds to give off solitary lightning bolts in single storms - which is where this story no doubt originates from.

I think it was most likely thunder & lightening. I remember seeing a BBC weather forecast mid last week which predicted thunder & lightening for Sunday afternoon/evening. Definitely not a sonic boom either, this wouldn't have generated a flash of light. A UFO crash landing on Greenham is the only other real explanation..........
